This turn-key GM 350CID engine comes fully assembled using a brand new (not remanufactured) GM 10067353 350cid 4 bolt main long block. We have preinstalled all name brand components needed to make this engine ready to run, right out of the crate.

Cylinder Head Notes: 7 Bolt style Exhaust Flange Standard, 85' and prior intake manifold bolt pattern. Perimeter bolt style Valve Covers. This head is very similar to the old #882 castings from the 1970's.

Performance Automatic, in its never ending quest to stay on top of today’s need for modern day transmission packages, has come up with an addition to its popular Street Smart Packages. The PAGM Series Street Smart Systems are exclusively designed to complement selected Chevrolet Performance Crate Engines. The Chevrolet Performance Crate Engines have been increasingly popular with Street Rodders and Muscle Car enthusiasts alike. Performance Automatic has developed customized overdrive transmission packages and has made it easy to pick a combination for your vehicle. The PAGM Series Packages have been designed for both performance and street ability. These kits also include all the necessary transmission components to complete the installation.

The PAGM TH350 kit utilized the Street Smart Converter that is designed to give that “stop light to stop light” performance and to stretch that tank full of gas running down the highway in lock up. The PAGM series also provides you with a complete hardware kit consisting of all the nuts and bolts needed for your particular combination.

Performance Automatic PAGM series transmissions are specifically designed and tuned for use behind most of the Chevrolet Performance crate engines. The PAGM transmissions include the proper torque converter, beefed-up internal components, shift patterns and pressures to match the Chevrolet Performance crate engines cam profile, HP rating, torque curve and RPM range. Each transmission is dyno tested.
